A New Public Key Cryptosystem Based on Edwards Curves
Elliptic curves Twisted Edwards curves RSA cryptosystem
2019/9/19
The elliptic curve cryptography plays a central role in various cryptographic schemes and protocols. For efficiency reasons, Edwards curves and twisted Edwards curves have been introduced. In this pap...
A Brief Retrospective Look at the Cayley-Purser Public-key Cryptosystem, 19 Years Later
public-key cryptography cryptanalysis
2018/3/15
The purpose of this paper is to describe and analyze the Cayley-Purser algorithm, which is a public-key cryptosystem proposed by Flannery in 1999. I will present two attacks on it, one of which is app...

2017/5/31
In this work, we propose a new public-key cryptosystem whose security is based on the computational intractability of the following problem: Given a Mersenne number p = 2^n - 1, where n is a prime, a ...
A Practical Post-Quantum Public-Key Cryptosystem Based on spLWE
practical post-quantum IND-CCA PKE
2016/12/7
The Learning with Errors (LWE) problem has been widely used as a hardness assumption to construct public-key primitives. In this paper, we propose an efficient instantiation of a PKE scheme based on L...
Cryptanalysis of a public key cryptosystem based on Diophantine equations via weighted LLL reduction

Applicable Public-Key-Cryptosystem NP-Complete Problems
2016/1/25
A new Public-Key-Cryptosystem is presented from which we think that it will survive against possible attacks by Quantum-Computers in the future. We analyse its performance and its expected security.

Extensive studies have been made of the public key cryptosystems based on multivariate polynomials
(Multi-variate PKC, MPKC) over F2 and F2m. However most of the proposed MPKC are proved not
secure....
This paper presents a new fast public key cryptosystem namely : a key exchange algorithm, a public key encryption algorithm and a digital signature algorithm, based on the diculty to invert the follo...
Oblivious Transfer from weakly Random Self-Reducible Public-Key Cryptosystem
Oblivious Transfer Public-Key Cryptosystem
2015/12/31
In this work, we define a new notion of weakly Random-Self-Reducibile cryptosystems
and show how it can be used to implement secure Oblivious Transfer. We also show that
two recent (Post-quantum) cr...
